MACHINE FOR CUTTING CHENILLE.

To all whom it may concern:

Be it known that I, GUSTAV HEDRIGH, technical instructor, residing at34: Meckelstrasse, Barmen, Prussia, Germany, have invented certain newand useful Improvements in Machines for Cutting Chenille, of which thefollowing is a specification.

The invention relates to means for cutting chenille bands or fabric,such as described in my United States Patent No. 954,470.

In the accompanying drawings, Figure 1 illustrates the machine in afront view; Fig. 2 in plan view of same, Fig. 3, a vertical section,showing the travel of the goods; Fig. 4, a detail view looking towardthe mandrels and illustrating the method of separating and cutting thethreads; Fig. 5, a detail side view of a knife and its mounting; Fig. 6,a plan view thereof; and Fig. 7, an edge view thereof.

The main characteristic of the invention is the fact that the fabric iscut by means of knives in the direction of the weft, the knives beingsecured to an endless chain, rope or band, and so moved thereby as topenetrate through and cut the fabric which is continually fed to them.

The machine shown in the accompanying drawing operates in the followingmanner: On a chain a (indicated in Figs. 1 and 2 by broken lines) arearranged, at certain distances apart, knife holders 6 (Figs. 5 to 7) soarranged as not to impede the movement of the chain around the guiderollers 0, (Z, as shown in Fig. l. The rollers, of which others are alsoarranged at the right hand side of the machine, are so located that thechain a is passed at the top in a straight line over a guide 2' which isprovided with a dovetailed recess to receive a correspondingly shapedsupport h carrying the knife clip or holder 6. The knife 6 is secured inthe clip by means of a toothed. nut which is prevented from becomingloose by means of a pawl g.

By means of the chain the knives are carried past a series of conicallyshaped mandrels 76 over which the tubular chenille fabric is guided inthe manner shown in Figs. 3 and 4:. As shown in Fig. 3, the material isfed over a beam Z toward the mandrels 71?, where it is cut and thenseparated to form the individual pile strips or hands, whence it isguided over grooved rollers m m toward the reel.

Serial No. 648,919.

Fig. 4 illustrates the operation of the man drels 70. They are destinedto enter the tubular fabric and to spread apart the upwardly anddownwardly directed weft portions. Arranged between the mandrels 7c arebrackets 11 n adapted to act as supports for the severed parts 0 of thematerial (Fig. 4c). The knives travel in the direction of the full line00 (Fig. 4) through slots 2? in the mandrels 7c, and alternately aboveand below the warp binding threads and cut the wefts in such manner thatthe long tufts are pressed upward and downward under the action of thetwist of the binding warp threads, so that short weft portions remainbetween the long pile tufts. The rollers m m are grooved (Figs. 1 and 2)thereby enabling the tufts 0f the chenille guided above them to enterthe grooves and to stand upright.

The described cutting device may be arranged directly on the weavingloom for making the preliminary chenille bands. In most cases, however,it will be advisable to construct the cutting machine as an independentdevice, as it is then possible to operate it quickly and enable acutting machine of this kind to cut the products of several looms.

WVhat I desire to claim and secure by Letters Patent is:

1. Chenille cutting mechanism comprising an endless conveyer,independent knives mounted on said conveyer, and slotted mandrelsthrough which said knives pass when in motion, substantially as setforth.

2. Chenille cutting mechanism comprising an endless conveyer,independent holders on said conveyer, independent knives mounted on saidholders, guides for said holders and slotted mandrels through which saidknives pass when in motion, substantially as set forth.

3. Chenille cutting mechanism comprising an endless conveyer,independent knife holders on said conveyer, independent knives mountedon said holders, guides for said holders, slotted mandrels through whichsaid knives pass when in motion, and alternately upper and lowersupports between the mandrels substantially as set forth.

at. Chenille cutting mechanism embodying means for opening up orspreading apart the weft portions of the chenille fabric, meansaffording alternately raised and depressed binding points for thefabric, and a cutter adapted to travel in a line alternately above andbelow the warp binding threads, whereby the weft threads are cut and Intestimony whereof I afiix my signature 1n presence of two witnesses.
